Hi, saw your comment about recording MAME games. I do like this (should work on all MAME UI versions, i use MAME Plus):

Right click on the game you wanna play and record input.

If you're happy with the game open it from the file tab and you should come back to a window called play. Now go into the snaps folder (you gotta have a /inp and /snap folder in your main MAME directory) and enter the name of your file and click ok. Now it plays the input file in MAME and records an uncompressed AVI file in your snaps folder. Use Virtual Dub or other video software to compress.
